-/**
- * 面相对象辅助类，可实现类的创建，继承，方法重写
- *
- <pre>
- //-------------------------
- // JS类的创建,继承
- //-------------------------
-
- // 例子1:-------------------------
- // 创建一个父类
- var Person = Class.create({
-        // 构造函数
-        init:function(option){
-            this.name = option.name;
-        }
-        ,getName:function() {
-            return this.name;
-        }
-    });
-
- // 声明类实例
- var Jim = new Person({name:'Jim'});
- console.log('Jim name:' + Jim.getName())
-
- //例子2:-------------------------
-
- // 创建一个类,继承Person类，并重写getName
- var Man = Class.create({
-        init:function(option) {
-            this._super(option);// 调用父类构造函数
-            this.age = option.age;
-        }
-        // 重写父类方法
-        ,getName:function() {
-            // 调用父类的getName()
-            var name = this._super();
-            return '我重写了getName方法：{'+name+'}';
-        }
-    },Person);
-
- var man = new Man({name:'Tom',age:22});
- console.log('man name:' + man.getName())
-
- console.log('Jim instanceof Person: ' + (Jim instanceof Person));
- console.log('man instanceof Person: ' + (man instanceof Person));
